Alpha, Beta, Gamma in ascending order.

Alpha particles leaves the nucleus of an unstable atom at a speed of 16,000 kilometres per second, around a tenth the speed of light.
Beta particles travel at a speed of 270,000 kilometres per second, around 98% of speed of light.
Gamma particles travel at the speed of light.

Achin conducted an experiment to find out the amount of light that can pass through three different materials, a clear plastic sheet, a cardboard and a piece of tracing paper. All the materials have the same thickness. He shone a torch on the three materials and used a light sensor to measure how much light has passed through each of them. Which of the following graphs most likely shows the amount of light that has passed through each material?
